Quick memory/resource management question

[TarMaC]

I'm trying to conserve resources.

A svchost on my PC uses 24k many times and then reduces to 4k some times. I
understand basically
what a svchost is and does, and I know it may consists of many items, as in
this case.

My question is, how can I find out if those items it runs are really
necessary?

Below is what the svchost runs and what my situation/specs are. I'd
appreciate any advice on what's necessary or where I can find out more about
what's necessary.

My situation...
I run a non-networked, single user PC with online connection via Bellsouth
DSL (no hub or router).

This is what "tasklist" shows the one suspicious svchost runs...
AudioSrv, Browser, CryptSvc, Dhcp, EventSystem,
FastUserSwitchingCompatibility, helpsvc, HidServ, lanmanserver,
lanmanworkstation, Netman, Nla, RasMan, Schedule, seclogon, SENS,
SharedAccess, ShellHWDetection, srservice, TapiSrv, Themes, TrkWks, W32Time,
winmgmt, wscsvc, wuauserv, WZCSVC

Most all of the Processes/Services that run from within a SvcHost
are still controlled by the MMC Services. For example, SecLogon
is Secondary Logon. Svchost instances are bundled by Registry
settings where they are started at System Boot.
When you disable the Service that starts via SvcHost then it will
not appear in a Tasklist /SVC next time the PC boots.
Your best guide for how to modify Windows XP services is still
Black Viper's Web site. One word of Advice, Before changing the
Start Modes export the Services list as a reference to how they
were originally set.

I'll check that out. Thanks for the advice.

You've got plenty of memory unless you are running a heavy application that
you know required more than 256MB.

Here's my list of XP services that can be safely turned off. It predates
SP2 and I'd appreciate any thoughts as to what can be added or deleted.


Automatic Updates
Messenger Service
TCP/IP Netbios Helper
Wireless Zero Config (unless have a WiFI adapter in the machine)
Upload Manager
Task Scheduler Server
Error Reporting
Remote Registery
Server Service
Computer Browser

Turn off some of the GUI crap;

Start->Properties Select "classsic" IMHO

Start -> Control Panel > System -> Advanced
-> Performance -> Settings

Select "adjust for best performance"
